Lets define a class of functions. These functions will map from the positive integers to the positive integers and must satisfy the following requirements:
The function must be Bijective, meaning that every value maps to and is mapped to by exactly one value.
You must be able to get from any p...
Your task today is to apply a wave to an array of numbers. A wave looks like this: [1, 0, -1, 0, 1, 0, -1] Applying it to a given array means adding together the first elements, the second elements, etc.
More precisely:
Your program or function will recieve an array of integers. It must print o...
A repeating or recurring decimal is decimal representation of a number whose decimal digits are periodic (repeating its values at regular intervals) and the infinitely-repeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating (i.e. all except finitely many digits are zero). For example, the decimal representation of ⅓ becomes periodic just after the decimal point, repeating the single digit "3" forever, i.e. 0.333…. A more complicated example is 3227/555, whose decimal becomes periodic after the second digit following...
In mathematics, the repeating decimal 0.999… (sometimes written with more or fewer 9s before the final ellipsis, for example as 0.9…, or in a variety of other variants such as 0.9, 0.(9), or
0.
9
Ë™
{\displaystyle 0.{\dot {9}}}
) denotes a real number that can be shown to be the number one. In other words, the symbols "0.999…" and "1" represent the same number. Proofs of this equality have been formulated with varying degrees of mathematical rigor, taking into account...

ASCII quine quine we-really-need-an-ascii-tag
Your challenge is to write a program that produces output which has an ASCII value sum identical to the program source.
An example of an ASCII quine would be if the source code was ABC and the output was !!!!!!. This is because the sum of the the AS...
